It seems like so many of us have the same issues.
My mother has not been nice all my life. So these last few years have been even harder to deal with.
But, 2 months ago my mother had a stroke. She seems to have recovered okay from it, but it has warp sped her dementia! My 2 other sisters, well one tries to relieve me once a week, but the one that actually lives with my mother has been, well, not available. My mother couldn't go back to thier home, because it was filthy. So she came to stay with us while it got cleaned. (6 weeks later still not clean). I could deal with her I think though, if mom wasn't so nasty! She remembers things, but she cannot do everything herself. I just cry everyday, because she is just that mean. My 15 year old just avoids being in the same room, and I feel bad. Our home is usually lots of fun, but we all just tippy toe around.
I am sorry to say, I wish I could just take her someplace else till her home is ready. What do I do. I want happiness back in my home again....
